ABSTRACT

A hair clip includes a curvilinear upper clamping arm having a shape as a curved knurled member; a curvilinear lower clamping arm have a slightly curved bend up shape; and a hinge assembly, said upper clamping arm including two side ears, an elongated projections on an lower surface, said lower clamping arm including two side brackets, an elongated opening extending from a position adjacent of the other end to the side brackets, protrusions disposed on an upper surface at either side of the opening, and said hinge assembly including a torsion spring, pins through the side ears and the brackets. The upper clamping arm and the lower clamping arm set in a curved shape, the middle parts of the upper and lower clamping arms do not abut against each other to increase a large space for accommodating hair.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The invention relates to hair accessories, and more particularly to animproved hair clip capable of securely grasping and holding more hair inplace.

2. Description of Related Art

One conventional hair clip has no teeth. It is disadvantageous becauseless hair is grasped. Further, the hair clip is liable to slip out ofthe hair strands.

Another conventional hair clip has teeth. However, it is alsodisadvantageous because there is little space provided between twoopposite clamping arms in a closed position and in turn, limited haircan be grasped by the clamping arms. Further, open ends of the hair clipcannot be closed if there is more hair grasped by the clamping arms.

Thus, the need for improvement still exists.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1 to 7, a hair clip 1 in accordance with theinvention comprises a curvilinear upper clamping arm 10, a curvilinearlower clamping arm 20 and a hinge assembly 30.

The curvilinear upper clamping arm 10 having a shape as a curved knurledmember, curved forwardly bend upwards from the middle part and extenddownward forms an upward curved arc and further forms a tip 15 on thefront end, a curved backwardly bend downwards from the middle part andextend upward forms an downward curved arc and further forms a upperpress member 13 on the upper extend end.

Said curvilinear upper clamping arm 10 including two side ears 11extending downward and being adjacent between the upper press member 13and the tip 15, and a plurality of first elongated projections 121 and aplurality of second projections 122.

Each side ears 11 having an aperture 110 and an upper limited members111, the first and second projections 121, 122 disposed alignment on alower surface of the upper clamping arm 10 extending from positionadjacent of the side ears 11 to the tip 15. The second projections 122,selective forms adjacent to the side ears 11, which shorter than thefirst elongated projections 121.

A knurled member on an upper surface of the upper press member 13 foraiding in gripping, a cavity 14 on a lower surface of the upper pressmember 13 between the side ears 11, an upper well 141 in the cavity 14,the tip 15 on the front end of the upper clamping arm 10 enable parthair.

The curvilinear lower clamping arm 20 having a slightly curved bend upshape, the radian of the curved is smaller than that of the curved ofthe upper clamping arm 10, including an elongated opening 22 form on themiddle portion of the lower clamping arm 20, a lower press member 25form on the rear end, two side brackets 21 extending upward and beingadjacent to one end between the lower press member 25 and the elongatedopening 22, each side brackets 21 having a through hole 210 and a lowerlimit members 211.

The elongated opening 22 extending from a position adjacent to the otherend to a position adjacent to the side brackets 21 corresponding withthe first and second projections 121, 122 to enable the projections passthrough the opening 22, and a plurality of protrusions 23 disposed on anupper surface and at either side of the opening 22 for an anti-slippurpose, a cavity 24 on the upper surface between the side brackets 21and one end, a lower well 241 in the cavity 24, a wavy member on a rearportion of a bottom surface of the lower press member 25 for aiding ingripping.

The hinge assembly 30 including a torsion spring 31, a pivot pin 32 anda plug pin 33. Said torsion spring 31 disposed between the side brackets21 and having one end anchored in the upper well 141 and the other endanchored in the lower well 241, a pivot pin 32 inserted through theapertures 110, the through holes 210 and the torsion spring 31 to fastenat an outer surface of one side ears 11, and a plug pin 33 inserted intothe pivot pin 32 to fasten at an outer surface of the other side ears11.

It is noted that the ends of the torsion spring 31 may be disengagedfrom the upper well 141 an the lower well 241 when the hair clip 1closes if there is no provision of the upper and lower limit members111, 211. To the worse, the curvilinear upper clamping arm 10 or thecurvilinear lower clamping arm 20 may be broken due to the torque of thetorsion spring 31. In short, the upper limit member 111 against thelower limit member 211 to prevent the curvilinear upper clamping arm andthe curvilinear lower clamping arm 20 from is deformed or fractured.

As shown, the total number of the first projections 121 and the secondprojections 122 are eight. Alternatively, the number of the firstprojections 121 and second projection 122 may be changed depending onapplications. For example, the number of the first projections 121 isincreased when the hair clip is large or the number of the firstprojections 121 is decreased if the hair clip is small, the number ofthe second projection 122 also may be changed accordingly. The firstprojections 121 and the second projection 122 may be formed in one lineup, two lines up or staggered in one line, two lines, respectively.

Principles are that when forms the second projections 122 adjacent theside ears 11, the finger holding the hair clip 1 open for clipping hair,the hair strands not be jammed by the shorter second projection 122forms near the fulcrum of the side ears and the side brackets, and whencompleted clip the hair and closed the hair clip 1, the firstprojections 121 pass through the opening 22 for aiding in grippingsteady.

In a closed position of the hair clip 1, most of the first projections121 pass through the opening 22. An individual may use one finger topress the knurled member of the upper press member 13 and use the otherfinger to press the wavy member of the lower press member 25 toward eachother to open the hair clip 1 and energized the torsion spring 31.Thereafter, hair strands can be placed between the first projections121, the second projections 122 of the curvilinear upper clamping arm 10and the opening 22 of the curvilinear lower clamping arm 20. Next, theindividual may release the elastic force of the torsions spring 31 ofthe upper clamping arm 10 and the lower clamping arm 20 to close thehair clip 1. As a result, the hair strands are securely grasped and heldin place by first projections 121 through the opening 22 and theprotrusions 23 in the closed position. And the front end of the lowerclamping arm 20 abuts against with the inner side of the tip 15 of theupper clamping arm 10.

The invention has the following characteristics and advantages: Morehair is cross lock and held in place via the first projections passthrough the opening and the protrusions setting hair but without tugginghair. It could also clip less hair steadily. The curved knurled type ofthe curvilinear upper clamping arm and the curved bend up shape of thecurvilinear lower clamping arm, which the radian of the curved issmaller than that of the curved of the upper clamping arm to providemuch more space than a conventional hair clip, it is effective to holdfine hair or thick hair in place.
